1. Operate bimetal switch
If the main body is not cooled enough, the bimetal switch operates, and only the heater is
turned off. (The indication of the operating state is normal.)
If you can release it by pressing the rod-shaped switch on the bottom of the main body but
resolve a cause, and we recommend that you request a repair or inspection.

because it is difficult to identify the cause.
